My advice would be to screw up your courage, bite the bullet, and
convert to UHD.

Theres a UHD utility, usrp2_addr_burner that can be used to change the
IP address.

The factory address is:, you'll need to change it to an
address on a different
  subnet, like  or some such.  The idea is that you have
two GiGE ethernet ports,
  and you configure your system with the appropriate subnet on each
ethernet port, and program your
  USRP2 addresses accordingly.
